Your stack, one stock ledger.
Native connectors, not zaps: credentials in an encrypted vault, every external call logged, every outcome audited. GS1 barcode generation is live today — real, retail-scannable GTINs allocated from your own GS1 US account.
The same UPCs retailers and marketplaces verify against — allocated, registered and stamped without leaving your catalog.
GS1 barcodes, generated where your items already live.
Barcoding usually means a spreadsheet, the GS1 portal in another tab, and re-keying GTINs back into your system — one typo away from a mislabeled product. Invistock talks to GS1 US Data Hub directly, so a barcode is one run, not an afternoon.
Built and building.
Roadmap order follows demand — if the tool you run is below, say so on a call and it moves up the list.
Allocate real GTIN-12s from your own GS1 US account, register each product with GS1 and stamp the barcode on the item — audited end to end.

Marketplace orders into your normal fulfillment flow, FBA-aware stock views.

Integration questions
Yes — and that's the point. You connect your own GS1 US account (an API key and your account ID; your company prefix is discovered automatically), so every GTIN Invistock allocates is registered to your company and stays yours even if you leave.
Watch a GTIN land on your item.
Bring your GS1 US account to the call — we'll connect it, run a live barcode allocation on your own SKUs, and walk the roadmap for the rest of your stack.
